The spotted lanternfly, first found in Maryland in 2018, is a pest that threatens agriculture, ecosystems, and residential areas. It feeds on over 70 plant species, including grapes, apples, and stone fruits, weakening and sometimes killing plants. The pest also produces honeydew, leading to black mold that damages surfaces and disrupts ecosystems. Maryland has implemented quarantine measures across 19 counties and Baltimore City to slow its spread.
Key Points:
- Identification: Egg masses (fall-spring), black-and-white nymphs (spring-summer), and red-winged adults (summer-fall).
- Host Plants: Tree-of-heaven, fruit trees, hardwoods, and ornamentals.
- Control Methods:
- Physical: Scrape egg masses, use tree bands, and crush insects.
- Environmental Adjustments: Remove tree-of-heaven and encourage natural predators.
- Chemical: Use EPA-approved insecticides as a last resort.
- Reporting & Compliance: Report sightings to the Maryland Department of Agriculture and follow quarantine rules to prevent spreading the pest.
Stay proactive by inspecting your property regularly, removing egg masses in winter, and controlling adults in late summer. Professional landscaping services can help manage infestations effectively while following state regulations.
Spotted Lanternfly Control and Management
How to Identify Spotted Lanternfly and Its Life Cycle
Spotting a spotted lanternfly early is crucial to preventing infestations. This pest changes noticeably at each stage of its life, so knowing what to look for throughout the year is key.
What Spotted Lanternfly Looks Like at Each Stage
Egg masses are often missed but are critical to identify during winter and early spring. These gray, mud-like patches are found on tree trunks, outdoor furniture, vehicles, and other surfaces. Covered with a waxy coating that cracks over time, they’re easy to mistake for dried mud or lichen, which is why they often go unnoticed until hatching begins[4].
In April and May, nymphs hatch and start their four-stage development[2][4]. Early-stage nymphs are black with white spots, while later stages develop bright red patches alongside the black-and-white markings, making them easier to spot[2][4].
Adults, the most recognizable stage, appear in late summer. They are about 1 inch long, with gray forewings covered in black spots[3][2]. When they spread their wings, their bright red hindwings become visible, making them hard to miss. Adults stay active through September or October, peaking in visibility during the summer.
| Life Stage | Appearance | Timing in Maryland | Where to Look |
|---|---|---|---|
| Egg Mass | Gray, mud-like, ~1 inch long | Fall–early spring | Tree bark, rocks, vehicles, furniture |
| 1st–3rd Instar Nymph | Black with white spots | Late spring–early summer | Host plant stems, leaves |
| 4th Instar Nymph | Red with black and white spots | Early–mid summer | Host plant stems, leaves |
| Adult | Gray forewings, red hindwings, ~1" | Mid-summer–fall | Tree-of-heaven, grapevines, fruit trees |
By recognizing these stages, you can focus inspections on the right plants and surfaces at the right times.
Host Plants and Where They Live
The tree-of-heaven (Ailanthus altissima) is the favorite host plant of the spotted lanternfly[3][2][4]. This invasive tree, identified by its smooth bark and compound leaves, often harbors the heaviest infestations. If this tree is on your property, inspect it frequently.
Spotted lanternflies also target a variety of other plants common in Maryland, including fruit trees like apples, grapes, and stone fruits, as well as hardwood trees such as maples and walnuts[3][2][4]. Even hops and ornamental plants aren’t safe from these pests[3][2][4].
When inspecting, focus on tree trunks, branches, and the undersides of leaves on these host plants. Don’t forget to check nearby structures and outdoor equipment, as egg masses are often laid on these surfaces. Even if you don’t have tree-of-heaven, infestations from nearby properties can spread to yours.
Seasonal Life Cycle Timeline
Understanding the seasonal life cycle of the spotted lanternfly can help you time your inspections effectively. Egg masses are laid in late fall and remain dormant through the winter until they hatch in spring[4].
From May through July, nymphs are active, transitioning from black-and-white early stages to larger red-and-black forms[2][4]. This is a critical period as nymphs move around and feed, causing visible damage to plants.
Adults emerge in late July and stay active through September or October, during which time they mate and lay new egg masses[3][4].
Spring is the best time to remove egg masses, while late summer is ideal for spotting and controlling adults. Regular inspections during these periods can help you catch infestations early.
When inspecting your property, use a flashlight to check tree bark crevices and outdoor surfaces carefully. Take photos and document the locations and stages of any findings. Sharing this information with the Maryland Department of Agriculture can help track the spread of this invasive pest.
IPM Strategies for Spotted Lanternfly Control
Now that you know how to identify the spotted lanternfly, let’s look at some effective ways to manage infestations. Integrated Pest Management (IPM) combines physical, environmental, and chemical methods to reduce spotted lanternfly populations while protecting your landscape and beneficial species. This approach starts with the least harmful methods and escalates only when absolutely necessary.
Physical Control Methods
Start with physical removal techniques. One simple yet effective method is egg mass scraping. Between late fall and early spring, check tree trunks, outdoor furniture, vehicles, and other surfaces for egg masses. Scrape them into a sealed plastic bag containing hand sanitizer or rubbing alcohol (wear gloves for safety), then dispose of the bag in your regular trash.
Another option is tree banding, which helps trap nymphs as they climb host trees during spring and early summer. Wrap a sticky band around tree trunks and inspect it regularly to remove trapped insects.
For smaller infestations, crush nymphs and adults by hand or submerge them in soapy water. Early morning, when the insects are less active, is the best time for this method.
Cultural Control Methods
Cultural strategies involve altering the environment to make it less appealing to spotted lanternflies. A key step is managing or removing tree-of-heaven, the pest’s favorite host. Simply cutting it down won’t work – removal must include the root system or targeted herbicide treatments on cut stumps to prevent regrowth.
Encouraging natural predators can also play a role. Spiders, assassin bugs, yellowjackets, European hornets, praying mantids, and certain birds are known to feed on spotted lanternflies. Maintaining a pesticide-free, biodiverse landscape supports these beneficial species.
Additionally, good sanitation practices can help limit the pest’s spread. Inspect outdoor furniture, vehicles, and equipment for egg masses before moving them, especially during the fall when egg-laying occurs. Removing these masses can significantly reduce the chance of transporting the pest to new areas.
These methods work best when combined, creating a layered defense against infestations.
Chemical Control Methods
Chemical treatments should only be used when physical and cultural methods aren’t enough to handle severe infestations. Opt for EPA-approved insecticides and have them applied by trained professionals. These include systemic treatments absorbed by trees and contact sprays for immediate results.
Timing is key: treat nymphs in late spring to early summer and adults in late summer, before they lay eggs. To protect pollinators and other beneficial insects, avoid spraying during peak activity hours or on flowering plants. Applying treatments in the evening can help reduce unintended harm.
Recent data from 2023 highlights the growing role of natural predators in controlling lanternfly populations, reinforcing the value of integrated approaches. For example, in Columbia, Maryland, a combination of egg mass scraping, tree banding, tree-of-heaven removal, public education, and monitoring has proven effective at managing infestations while minimizing chemical use[5][6].

Monitoring, Reporting, and Following Maryland Regulations
Keeping the spotted lanternfly in check requires diligent monitoring and timely reporting. Maryland has established specific rules to combat the pest’s spread, and property owners are a critical part of the solution. Here’s how you can inspect your property effectively throughout the year and stay compliant with state regulations.
How to Inspect Your Property
Regular inspections are your best defense against a spotted lanternfly infestation. The focus of your efforts should shift with the seasons to align with the pest’s life cycle.
From late fall through early spring, keep an eye out for egg masses. These are often found on tree trunks, outdoor furniture, vehicles, fences, and other surfaces. Using a flashlight can help you spot them more easily. As temperatures rise in late spring and summer, turn your attention to nymphs and adult lanternflies, especially on plants. The tree-of-heaven (Ailanthus) is a favorite host for the fourth instar nymphs, but don’t overlook other plants in your yard – they can also harbor these pests.
Be alert for telltale signs like black or red nymphs crawling on vegetation, adult lanternflies with their distinctive spotted wings, and honeydew, a sticky residue left by the insects. In severe infestations, you might even notice honeydew dripping from trees, which can attract sooty mold.
Whenever you spot evidence of the pest, document it. Take clear photos and note the location to assist state tracking efforts.
How to Report Spotted Lanternfly Sightings
If you identify spotted lanternflies on your property, report them immediately. Early reporting allows authorities to track infestations and take action to contain the pest.
You can report sightings through the Maryland Department of Agriculture (MDA) using their online form, by email at DontBug.MD@maryland.gov, or by calling (410) 841-5920. Include as much detail as possible: the date and location of the sighting, the number of insects, and their life stage (egg, nymph, or adult). Photos are especially helpful, as is noting the type of plant or surface where the pests were found. This information helps experts assess the situation and prioritize their response.
Your timely report not only contributes to a statewide database but also strengthens efforts to manage and prevent the spread of the spotted lanternfly.
Maryland Quarantine Rules You Need to Know
Once you’ve reported a sighting, it’s important to understand Maryland’s quarantine rules, which are designed to curb the pest’s movement. Currently, 19 counties and Baltimore City are under quarantine, with restrictions on moving materials that could harbor lanternflies or their egg masses.
If you live in a quarantine zone, avoid transporting potentially infested items out of the area. Before traveling, inspect your vehicle, equipment, and belongings for egg masses or insects. If you find egg masses, remove and destroy them following proper disposal guidelines.
Businesses operating in quarantine zones have additional responsibilities. They must secure permits before transporting regulated items outside the zone, train employees on inspection procedures, and keep detailed records of inspections and shipments. Non-compliance can result in fines or other penalties.
Even if you’re outside a quarantine zone, adopting these inspection practices can help safeguard Maryland’s landscapes and agricultural resources from further infestations. For the latest quarantine details, visit the Maryland Department of Agriculture website.

Protecting Your Landscape with Professional Help
Managing your landscape effectively goes beyond just monitoring pest activity – it calls for a combination of pest control expertise and thoughtful landscape care. Tackling long-term spotted lanternfly issues means integrating pest management techniques with practices that nurture a healthy, sustainable yard.
Combining Pest Control with Landscape Care
Professional landscapers often rely on Integrated Pest Management (IPM) strategies that extend far beyond the use of chemicals. These methods include mechanical controls like removing egg masses and installing circle traps, cultural controls such as promoting healthy plant care, and applying chemical treatments only when absolutely necessary.
A healthy, resilient landscape is your best defense against pests. For example, planting a mix of native species naturally reduces the risk of widespread pest damage. Healthy soil, enriched with proper fertilization and organic matter, boosts plants’ natural defenses. On top of that, efficient water management helps minimize plant stress, making them less vulnerable to pests.
Spring is the ideal time to begin preventive measures for spotted lanternfly control. However, one major hurdle for homeowners in Maryland is that the Maryland Department of Agriculture does not offer residential treatment for these pests [1]. This makes hiring professional landscapers crucial for effective, integrated pest management. For tailored, hands-on solutions, professional help becomes a key asset.
